Case Sensitivity

Languages Focus

Case sensitiviy in this case is referring to commands and variable names. For example, are "printf" and "PrintF" equivalent? Are fullname and FullName equivalent? When you create commands, operations, methods, or variables should you worry about case?

Cross Reference Examples:

Access VBA:
No

Access VBA is not case sensitive. Like VB Classic, if you type any other case for command or variable names, Access VBA will change it to the "accepted" or "defined" case. For example, if you type msgbox it is converted to Msgbox.

ASP Classic is not case sensitive. My preference for all languages where case sensitivity does not matter is to use camel caps as in the first example above. Many developers coming from a case sensitive language prefer to use all lowercase.

In C# commands and variable names are case sensitive. The following does NOT:

messagebox.Show("hello"); //Does not compile!

The first time you type any other case for commands or variables, VS.Net will change it to the accepted or defined case. For example, if you type messagebox.show it is converted to MessageBox.Show. Once corrected, you can break it again by editing MessageBox to messagebox and the compiler will give you an error.

PHP is case sensitive with variable names but not with commands. Although commands are case incenstive, I prefer to use all lowercase because it's easy to type and that's what I see most PHP coders doing and I see it on PHP.Net.
